ME TAL SHELVING.

Specification of Letters Patent.

Application filed October 10, 1912. Serial No. 724,948.

Patented Mar. 25,1913.

T 0 all whom it may concern Be it known that I WALTER N. VANCE, a citizen of the Uniteo States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Metal Shelving, of which the following is a specification.

This invention relates to improvements in metal shelving, such for instance as is used in factories to form portable racks for receivin :01- holding various articles being manu actured or used. My improvement may also be used in many other instances where adjustable or replaceable shelves are employed, such for example as are used in stores ,for supporting merchandise or where shelves are employed forsupporting books.

The object of my invention is toprovide a strong, durable, easily manufactured shelving ,that may be'easily assembled and disassembled and which includes a bracing or. locking member that sitively prevents any loose play between t e parts after the nut is screwed home on the bolt.

More-specifically my invention embraces L-shapcd uprights, marge preferably of pressed or rolled steel, aii provided with a plurality of spaced holes, shelves, also preferably made of ressed or rolled steel, said shelves having epending flanges ,provided with holes adapted to aline and cooperatewith those in the uprights, interengaging wedge shaped ribs. and grooves on the shelves and uprights, a substantially rightangled brace member which may made either from a stamped piece of stecl or in,

the form of a casting, and having a prowl.- tion thereof adapted to enter the recesses or holes in the shelf flanges, and uprights, and bolts adapted to pass through recesses in the brace members and the recesses in the shelves and uprights, whereby the members when assembled may be easily tightened and locked in place by means of nuts threaded thereon.

My invention furthermore consists in the novel construction of arts and devices and in the novel combinations of parts and deices herein shown and described or claimed. In the drawings forming a part of {this snccifioation, Figure 1 represents a tlont eict ation of a structure embodying my improvements. Fig. 2 is a section of the stiucture shown in Fig. 1 taken on line 2-2 of 3- is'an enlarged sectional view Fig. 1. Q takpn on t e line 3-3 of Fig. 1'. Fig. 4 is an enlarged detail View taken on the line 4-1 of Fig. 1 and Fig. 5 is an enlarged detail sectional view taken on the line 55 of Fig. 3.

In the drawings 10 denotes the upright members to which are connected the shelves 11. The shelves may be of any desirable shape and the number of uprights used may be increased or diminished as desired. However, I have shown my improvements in connect-ion with shelves of rectangular shape and supported by an upright at each corner. Each of theuprights 10 1S L-shape'd in cross-section and is composed of'members 12 and 13, the member 13 having a;

wedge shaped rib 14 thereon at one,end.' The portion 12 of each of the uprights is provided with a lurality of spaced substantially elliptical recesses 15, each of these recesses being adapted to receive a bolt and a projection on the brace member. 1 Each of the shelves 11 consists of a horizontal or supportin portion 16 provided with depending fiangeportions 17 each of said flan e portions Having an inturned portion 18, t ese inturncd portions 18 bei formed only intermediate the corners of the shelf. At each corner the shelf is provided with a. portion adapted to fit the inner side of the L-shaped upri hts and consists of offset portions 19 an 20 and a V or wedge shaped groove 21 adapted to coiiperate wi h the rib 14 on the upright. The portions 19 and 20 are so ofl'set as to leave the depending flanges 17 of the shelf flush with the exterior sidesof the members 12 and 13 of the upright members. Each of the portions 19 is furthermore provided with a recess 22 correspondin in; shape and size to the recesses 15 oi the uprights 10.

Cooperating'with the uprights 10 and the shelves 11 at each corner: are brace members 23, each brace comprising a' substantially right-angled member having 'a projection 24 adapted to fit over he ,portion 21. The

brace member 23 is rovaded on its 0 po-' site edge with s a ,d projecting mem ers or feet 25 adapte (0 rest on the offset portion 19 of the flange of the shelf. Intermediate the projections 25 on the, brace member is a pro'ection 26 which extends beyond the flat aces of the members 25 and is adapted to extend into the recesses 22 and 15 of the shelf, and upright; member respectively. This brace 23 may be made of sheet metal but is preferably formed by a member havinga head thereon details of my improvements may bemade.

' tially as specified.

member, substantially as specified.

casting and is also preferably provided with a concave recess 27 on its outer face in which is adapted to seat the rounded face of the nut 28. The brace member 23 is also furthermore provided with a recess 29 alining with the recesses 22 and 15 all of said recesses being adapted to receive and retain a bolt 30 on which is threaded the nut 28.

It will be apparent that other forms of retaining members may be. substituted for, the nut and bolt 28 and 30, such for instance as I and threaded into the brace member 23. v

\Vith the structure which I have shown it is apparent that the shelves may be adjusted vertically on the uprights 10 by means of the recesses 15 in the uprights and that upon screwing home the nut 28 on each of, the bolts the members are rigidly and solidly connected together, and onaccount of the projection 26 fitting in the recesses 22 and 15, as perhaps more clearly shown in, Fig. 5 in dotted lines, there is no chancc of the shelf rotating or sliding on the upright. Furthermore by providing the offset por-- tions 19"and 20 at each corner of the shelf and the cobperating wedge shaped ribs and, grooves 14 and 21, I provide additional bracing means which prevent the shelf from oscillating on the uprights.

It is apparent that many changes in the without departing from the spirit ofthe invention and all. such changes are contemplated as fairly come within the scope of'the appended claims.
